- New York, N. Y., a corporation of New York Application November 17, 1944, Serial No. 563,918 (Cl. 346-104) 24 Claims.

.1 This invention relates to recording apparatus and more particularly to time recorders such, for

example, as a time recorder of the type assigned,

to individual workmen and used to record the time spent on each job and the cost of the labor and overhead to be assigned to each such Job. Time recorders of the latter type may be referred to as Job cost recorders or bench recorders.

An object of this invention is to provide a time recorder which is of improved construction and arrangement of parts and which operates in a simple and effective manner.

A further object is to provide an improved form of time recorder which functions to accumulate desired numerical data at a given time rate and which operates to record the totals of such data by applying data representing marks of electrically conducting material on a suitable record sheet such as a standard record card used a with electric accounting machines.

A further object is to provide a job cost recorder which when used by the workmen in a, production plant, keeps the oflicials constantly and accurately' informed of the time spent on each job and the cost thereof.

A still further object is to provide a time recorder which is durable and reliable in its opera- 4 tion and which provides an accurate record of each work assignment and which by its improved construction prevents its unauthorized manipulation by a workman in an attempt to distort the data.

Other objects of the invention will be pointed out in the followingdescription and claims and illustrated in the accompanying drawings, which disclose, byway of example, the principleof the invention and the best mode, which has been contemplated, of applying that principle.

In the drawings:

Fig. 9 is a plan section showing the base of the recorder and the elements of the card holder, the

on the longitudinal center line of a data recording pencil.

Fig. 13 isa. view showing one example of a record card on which the recorder shown in Figs. 1 to 12 inclusive, records accumulated data.

Referring now in detail to the drawings and particularly to Figs. 1 to 5 inclusive, and 9, a preferred embodiment of the time recorder is indicated generally by the reference numeral l0 and comprises a supporting frame structure includin a'horizontal base plate Ii and a pair of upstanding spaced supporting plates I2 and I3, respectively, extendin across the base H from front to rear thereof and suitably fixed at their lower ends to the base.

Mounted on the base plate I l and extending from the left-hand side, as viewed in Figs. 3 and 9, to the right-hand side thereof, is a card holder IS.

The card holder comprises a curved bottom plate [6 (see also Fig. 4) and a pair of upstanding side plates i1 and I8, respectively, having their upper longitudinal edges turned over toward one another and then downward and terminating short of the bottom plate to provide spaces therebetween of the proper dimensions for receiving the upper and lower longitudinal edges of a record card IS. The card 19 is preferably a standard type of card used to control operation of a well known commercial form of electric accounting machine. In Fig. 4, the card i9 is shown in its proper position in the card holder [5. The card is shown in enlarged detail in Fig. 13. In order to avoid confusion, the card has been omitted from Fig. 9. It is to be noted, however, that if the card had been shown in Fig. 9, it would have appeared therein in the same position as it appears in Fig. 13.

The card holder I is supported for limited longitudinal movement with respect to the base plate I I for a purpose which will presently appear. The card holder supporting means comprises .a

plurality of spaced rollers.20 mounted, respectively, within aligned openings extending through upstanding lugs 2! formed on the ends of bracket plates 22, the ends of each roller 20 extending through aligned slots 23 in the upstanding side plates I1 and H3. The bracket plates 22 are sultably fixed to the base plate II. The normal position of the card holder is that which is shown in the drawings. The card holder is moved only during a recording operation, as will later appear.

On the left-hand end of the card holder l5 as viewed in Fig. 9, is fixed a card throat -25 of suitable molded material and being formed with a curved slot 26 through which the card l9 may be inserted and removed endwise from the holder 15. The throat 25 occupies a suitable recess in an end wall of an enclosing casing or cover 21 of the recorder and is movable with the rest of the card holder. The card holder is provided at its right-hand end with-upstanding spring fingers 28 which are fixed to an end plate 29 of the card holder and extend upwardly through suitable openings 30 provided in the curved bottom plate I6. When a card I9 is fully inserted within the holder IS, the right-hand end of the card engages the fingers 28 and holds the latter in a deflected condition so that at the end of a recording operation when the card is released the fingers 28 will partially eject the card I! from the card holder.

The card is held within the card holder at all times when the recorder is operating by a card latch (see Figs. 9 and 10). The latch comprises an arm 32 fixed at one end to a shaft 33 journaled in spaced brackets 35 extending inwardly from the side plate ll. The arm 32 moves within a recess 36 formed in the throat 25 and moves from a non-operating position where its outer end 31. is below the card slot 26 to an operating position shown in Fig. 10 where the end 31 is across the slot 26 and engaging the left-hand end of the card l9 to hold the latter in its fully inserted position. The card latch is operated by a second arm 38 fixed at one end to the shaft 33 and connected at its outer end to the lower end of a link 39, the upper end of the latter being pivoted to the outer end of one arm of a rocker lever 40 (see also Figs. 1 and 3) which is in turn pivoted on a fixed stud 4| projecting from the vertical support plate [2. The other arm of the lever 40 is connected at its outer end to the lower end of an operating link 42 and the latter is pivoted at its upper end to one arm 43 of a bell crank lever 45 which is fulcrumed on a fixed stud l6 projecting from the connected levers and linkage Just described are a prise a engagement with the cam by of a second pair of radial arms constantly urged to move in a direction to latch the card by a spring 67 connected at its lower end to the pivot pin 58 connecting the link 62 and lever 8D, and connected at its upper end to a stud t9 projecting from the plate 12.

The time recorder dis-closed herein includes an operating mechanism which operates at a predetermined time rate. In so far as certain of the broader aspects of the present invention are concerned this operating mechanism may be of any suitable type such, for example, as a springdriven, marine-escapement clock movement, a time mechanism operated by minute impulses from the controlling electrical circuit of a clock system, or the operating mechanism may comsynchronous or frequency controlled A. C. motor. In the preferred embodiment disclosed herein the time operating mechanism comprises a frequency controlled A. C. motor of well known form which is suitably supported from the vertical plate l2 by studs 5| and 52 and includes a. motor drive shaft 58 to'which is fixed a pinion meshing with a gear 56 rotatably mounted on a stud 51- also projecting froin the plate i2. Fixed to the gear 56 is a driving cam 58. The motor shaft 53 operates at one (1) R. P. M. and the pinion 55 and gear 56 are of such relative sizes that the driving cam 58 is rotated at one tenth (1%) R. P. H.

Coacting with the cam 58 is a cam follower 59 which is pivotally supported by a stud 80 projecting from the support plate l2 and is held in a. tension spring 6! connecting a tailelement 62 of the follower with a fixed stud 63 on the plate I2. The cam follower is formed to include a gear sector 65 which meshes with a mutilated gear 66 formed on one end of a sleeve 61, the latter being rotatably supported within an opening provided through the support plate l2 and encircling a start shaft 88 which extends through both support plates I2 and I3 (see Fig. 5). Fixed to the sleeve 61 at the side of the plate l2 opposite to the gear 66,

is a hub 69 having a. pair of radial arms I0 which are connected at their .outer ends to one end of a semi-cylindrical driving plate II, the other end of such plate being connected to the outer ends nate inwardly in a second hub 13 journaled on the start shaft 68 adjacent the support plate. From the foregoing, it is apparent that with the cam 58 rotating at the rate of 1% R. P. H., the follower 59 is oscillated once each 1's of an hour and the driving plate H is also oscillated once each 1*; of an hour through its connection with the follower 59, which, as just stated, includes the gears 65 and 66, the sleeve 51 and the arms H.

The preferred embodiment of time recorder disclosed herein also includes a register comprising a, totalizing or accumulating mechanism which may be operated to accumulate desired numerical data at a predetermined time rate. The accumulating mechanism comprises generally a plurality of accumulator order elements 15 rotatably supported by the start shaft 68, a data entering means for each of the order elements l5, and an entry control means, which includes the driving plate II and which may be adjusted to enter any desired digital value representation into any order element during each oscillation of the plate H which, as stated above. occurs each of an hour while the recorder is in operation.

I2 which termiream Each accumulator order element is shown as comprising a ratchet wheel I8 having sixty teeth thereon. Each time a ratchet wheel I8 is advanced counterclockwise, as viewed in Fig. 4, by the entering means, a distance equal to one tooth space, such advance represents an entry. in that order of one unit of digital value. The data entering means for each order element, or ratchet wheel, comprises an arm 11 arranged alongside its related ratchet wheel and rotatably supported at one end on the start shaft 88. Each arm 11 carries an advancing pawl I8 which operatively engages the teeth I8 oi its related ratchet wheel I8 to move the latter counterclockwise. Each pawl I8 is pivotally connected. to its related arm 11 by a pin 88 extending th'fough an opening in the pawl and through an arcuate slot 8| formed in the arm. The length of the slot 8| is equivalent to one tooth space on a ratchet wheel I8. Each pivot pin 88 is normally held in the lower end of its slot by a tension spring 82 connecting the related pawl and arm. Each pawl carrying arm I1 is formed with an integral outwardly ex tending projection 88 which moves within a related slot 88 (Figs. 4, 5 and 11) formed in the semi-cylindrical driving plate II.'

The driving plate II forms one element oi theentry control means and the latter also includes presettable stops 88, which are selectively positionable, respectively, within pairs of transversely aligned radial grooves 81 formed in the sides of the slots 88. As shown in Figs. 5 and 11 there is one slot 85 for each pawl-carrying arm 11 and its related order ratchet wheel I8. There are nine pairs of arcuately spaced grooves 81 in each slot 88 and they represent, respectively, the nine digits "1 to "9 inclusive. When a settable stop 88 occupies a selected pair of grooves 81 in one slot 88 and the drive plate II is oscillated by the means previously described, once each 1 5 of an hour, the digital value corresponding to the position of such settable stop is entered in the related order ratchet wheel.

The plate II moves through an arc of 63 during each oscillation. Each 6 of such angular movement of the plate 'I| corresponds to an angular movement of one tooth space of the ratchet wheels. The. remaining 3 of angular movement of the plate 1| is provided so that the pawls 18 at the upper end of their clockwise movement will override slightly the ratchet teeth and thereby assure engagement with the correct ratchet teeth. It will be noted from an examination of Figs. 1, 4, and 6 of the drawings that the follower 59 is shown at the peak of the cam 88 and the plate II correspondingly is at the upper end of its clockwise movement. Each of the pawls is shown as being tooth space beyond a ratchet tooth. When the follower 59 drops of! the high point of the cams 58, the plate II quickly moves counterclockwise for the 63 under force of the spring 8| to effect entering of the digital values represented by the selected position of the stops 88 in the slots 85.

The digital value entry in each order is eiiected during such counterclockwise movement of the plate by the upper end 88 of its related slot 88 engaging the projection 83 oi! its related arm 11 and moving such arm 11. its pawl I8 and its ratchet wheel I8 counterclockwise an amount determined by the angular position occupied by the projection 83 of such arm at the time it is engaged by the end 88 of the slot 85. This angular position of each such projection 88 at the beginning of its counterclockwise movement is deterentry of the carry unit of value.

8 mined by the position oi the stop 88 in its related slot". At the lower end of the movement of the plate II, the ends 88 of all slots engage their related proiections 88 of the pawl carrying arms 11. When the plate 'I| moves upward and clockwise the projections 88 andtheir pawl carrying arms 11 will not move clockwise therewith until such projections are engaged by stops 88 in their related slots 88. Therei'ore, the amount of clockwise movement of each projection and its pawl.

carrying arm and the angular position of each such projection at the end oi such clockwise movement depends entirely upon the position of the stop 88 inits related slot 88. The digital values corresponding to the diiierent pairs of grooves in each slot 88 are indicated in Figs. 4 and 6 by corresponding numerals above the grooves and in Fig. 11 by corresponding numerals along the right-hand side of the plate and opposite the grooves.

In Fig. 4 a stop 88 is shown in the "9" digit position and the plate II is shown at the end of its upward or clockwise movement. Thus, when the plate I| moves counterclockwise, the pawl I8 will move the related ratchet wheel an amount equivalent to nine tooth spaces which represents a digit entry of nine in such ratchet wheel. The 63 angular degrees of counterclockwise movement of the plate II is the equivalent of 10% teeth of travel or the ratchet wheels. The first 3 01 counterclockwise movement of the plate and pawl will bring the .pawl into operative engagement with the ratchet tooth. In order to'provide a digit value entry of only nine in a ratchet wheel when the plate 'I| moves the arm 'I! for the-remaining 60 of its counterclockwise movement, such as will bethe case when a stop 88 occupies the position shown in Fig. 4, the related pawl I8 is stopped by the up er end 88 of a stop arm 8| engaging an outward projection of the pivot pin 88 when the pawl I8 has moved 54 of the remaining oi movement of the plate I I The 54 corresponds to nine tooth spaces of movement oi the ratchet wheel I8. When the pin 88 strikes the end 88 of the arm 8|, further counterclockwise movement 01' the pawl I8 and ratchet wheel I8 is prevented.

However, the plate Ii and arm 11 are permitted As will be apparent. a similar operation also takes place upon the entry of any of the digit values "1" to "8," inclusive; 1. e. during each entering operation, the plate 'I| moves the projection 88 and its pawl carrying arm 'II an angular distance equal to 6, or one tooth space, more than the pawl I8 is moved. when the stop arm 8| occupies its normal position shown in the drawings.

The just-described extra one tooth space of movement of the plate 'II and arm 11 is utilized when it is desired to enter a carry unit oi digital value in a higher order element, which occurs when the next lower order element is moved from 9 to 8." When the latter is to take place, the arm 8| normally in the path of the pivot pin 88 for such higher order element, is moved clockwise out 01 the way or such pin 88 by the next lower order element; and, as a result, the pawl I8 and ratchet wheel I8 of such higher order element are moved by the arm I! the angular distance corresponding to the digit value .to be entered in the normal way in such higher element, plus the extra one tooth space to effect t For example, it the stop for such next higher order element is set at the "5 digit position, the related pawl carenemies age order element, like the ratchet wheel I8 in Fig.

6, then there would be no stop 86 set in its related slot 85 of the plate II and whenits arm 9| is moved out of the path of its pin 89 by the next lower order element to effect the. entering of a carry, the ratchet wheel 16 of the higher order will only be advanced the one tooth space.

The carrying means will be understood more clearly from an examination'of Figs. 4, 5, 6, '7, and 8. Each ratchet wheel is provided with six lugs 92 oircumferentially spaced so that each time a ratchet wheel representing a lower order is advanced from a position representing the digit "9 to the position representing the digit 0," one of the lugs 92 engages and moves a related trip lever 94 clockwise, as viewed in Fig. 6, about a support shaft 95 extending between the two main support'plates I2 and I3. The left-hand end of each trip lever 94 as viewed in Figs. 4

and 6, is formed to provide a two-step position-' ing stop for the arm 9| of the ratchet wheel of the next higher order. The arms 9| are pivotally supported on a shaft 96 which is in turn supported at its ends by the support plates I2 and I3. The arms 9| are held in either of the step positions of its coacting trip lever 94 by a tension spring 91. The normal position for the arms 9| and coacting trip levers 94 is that shown in the drawing. When a lug 92 of a lower order trips a lever 94 and moves it clockwise, its spring 91 moves its coacting arm 9| clockwise so that a pin 98 carried by such arm 9| engages the lower step position of the lever 94 and the arm 9| then is in the position where the pin 89 of the next higher order element will not engage the end 99 of such arm (see the dotted line position of the end of the arm 9| indicated in Fig. 6). The several arms 9| and coacting trip levers 94 are restored to their normal position shown during the next upward or clockwise movement of driving plate 1|, by means of depending arms 99 on the hubs 69 and I3 operatively engaging, respectively, a pair of arms |9| journaled on the ends of shaft 96 and connected by a bail I92 (see also Fig. 5). Whenthe arms 99 are moved clockwise as viewed in Figs. 4 and 6 along with the driving plate, such arms 99 move the arms |9| and ball I92 counterclockwise into engagement with any of the arms 9| which were tripped to effect the entering of carry units during the entry portion of the preceding cycle of operation. The ball I92 moves the arms 9| counterclockwise to the normal position shown and the springs 91 move their coacting trip levers 94 back to the position shown.

In the construction illustrated, there are fifteen 'order elements 15 (see Fig. 5) and they are composing the accumulator I95 accumulates tens of dollars, the second from the left accumulates units of dollars, the third tenths of dollars, the fourth hundredths of dollars: the flfth thou- I sandths of dollars, and the sixth ten thousandths of dollars. The accumulator I98 is composed of the six order elements F5 to the left of the ac-.

cumulator I95, and is used to accumulate the labor cost for the job. The legend Labor" appears in Fig. 5 above the order elements of this accumulator. Like the accumulator I95. the order element 15 at the left of the group composing the accumulator I96 accumulates tens of dollars, the next one to the right thereof accumulates units of dollars, the next tenths, the next hundredths, the next thousandths, and the sixth from the left accumulates ten thousandths. The accumulator I91 is composed of the three order elements at the extreme left of Fig. 5 and is used to accumulate the time required for each Job. The legend Hours" appears above this accumulator I91. The order element 96 at the right of the group composing accumulator I9? is used to accumulate tenths of hours, the next order to the left thereof stores units of hours, and the one on the extreme left stores tens of hours. The order elements at the extreme left of the accumulator I95 as viewed in Fig. 5, and the order element at the extreme left of accumulator I96 are not provided with trip levers 94, the reason being to prevent carrying operations between accumulators.

One example of the manner in which the recorder may be usedto accumulate digital values, is indicated in Fig. 11 by the positions of the stops 86 in the pairs of grooves 81 in the slots 85. As Fig. 11 shows the outer face of the driving plate 1 I, which is the one opposite to that shown in Fig.

5, the positions of the slots 95, Fig. 11, corresponding, respectively, to the order elements 75 of the accumulators I95, I96, and I91, are reversed with respect to their positions shown in Fig. 5. The the slots 85 and no stops 86 are shown in the other corresponding to the accumulator I97 which stores units of time. The legend Hours appears at the top of these three slots. A stop 86 is shown in the 1 digit position of the left-hand one of the slots 85 and no stops 86 are shown in the other two slots. With this arrangement one digital unit of time is entered into the corresponding tenths order of the accumulator I91 each of an hour. As no stops 85 are in the other two slots 85 of the accumulator I91, the order elements I5 corresponding theretomerely store digital units of time which are entered therein by the carry means as explained above. The six slots 85 at the left of those just described are those corresponding to the order elements of the accumulator I96. The legend Labor. appears over the top of these six slots. The example selected for a labor rate is ninety-one and one-half cents an hour. Hence, thestops 86 are set in the proper slots to effect the entering during each of an hour in the order elements of the accumulator I96 digital values "representing nine hundred fifteen ten thousandths of a dollar ($09915). The legend ff'Burden" appears over the top of the six slots 85 at the left of Fig. 11 as these slots correspond, respectively, to the six order elements of the accumulator I95. The selected example of a, burden rate is one dollar and fiftyeight and one-half cents ($1.585) per hour. Consequently, stops 86 are so placed in the slots 85 under the word Burden" in Fig. 11 that each of an hour the plate II provides for the entering in the related order elements of accumulator I95 of digital values representing fifteen hundred and eighty-five ten thousandths of a dollar ($01585). It will be obvious that the order elements of both plates 11 accumulators Hi and H16 corresponding to the slots 85 shown in Fig. 11 with no stops 88 set therein, will function purely as storage orders.

From the foregoing, it will be apparent that, with the motor 58 operating, during each one tenth an hour one unit of digital value will be entered into accumulator I07, digital values representing $00915 will he entered into the accumulator I06, and digital values representing $01585 in the accumulator ltd. The drawings show the order elements in the positions they occupy after one entering operation has taken place and show the cam 5d, the plate it and the pawl-carrying arms il in the position they occupy just before the beginning of a second entering operation.

The recorder disclosed herein also comprises a mechanism which is operated by the workman when a particular job is finished, to record in one operation on the record card 59 in the card holder iii, the amount of time spent on the job which is standing in the accumulator it'll, the money value of the labor at the Workmans rate which is accumulated in the accumulator M8, and the money value of the burden or overhead cost at the predetermined rate which is standing in the accumulator Hit. To this end, each order element it of the three accumulators also comprises a star wheel Mil fixed to the side of its related ratchet wheel l6 and including six identical segments i l i, with each segment being formed at one side with ten positioning steps iii corresponding, respectively, to the ten digits ll through 9, and being formed on the opposite side as a radially er:- tencling straight edge M3. The lowest step lite of each segment corresponds to the digit and the highest step i it? the digit 9.

As shown in Figs. 3 and d, the recording mechanism comprises a plurality levers iii corresponding, respectively, to orders the accumulators, and pivoted at their upper ends on a shaft i it supported by the two plates i2 and i8 so that when a, recording is to be effected the levers MS may be moved in planes normal to the oi the star wheels MO. Each lever H5 comprises a downwardly extending arm ii? and a laterally extending arm l and is held in its normal posi tlon shown by a bail rod i l9 engaging the arms Mil of all of the levers. The hall rod lid is connected at its ends to spaced lever 32d fixed to a stop shaft E26 which extends through both supporting plates and 58. Each lever M5 is constantly urged to move in clockwise direction about its supporting shaft lit by a tension spring 922 connected at its upper end to a tail element 523 of such lever M5 and connected at its lower end to a rod 625 rernovaioiy held at its ends in slots i225 in brackets lid carried by the support 2 and i3 (see Figs. 1, 2, 3, and i). The arm i ii of each "lever i iii carries at its lower end a pencil barrel ltd (see Figs. 4 and 12) for slidably holding and guiding a lead which is made of a suitable electrically conducting ma= teriai and functions to place a marl: of this materlal in the proper index point or digit "position on the card when a recording is eil'ected. Each arm ii? is also formed with a cam finger iEitl which, when a recording is desired, is moved inward to engage a positioning st p M2 on the star wheel lid of its related order The step ii engaged by each finger fiiiii time its arm Hill is moved inward, is the one corresponding to the unit of digital value standing at that time in the order it of the accumulator of which the step M2 is a part.

With the exception of the denominational oriii) alignment is maintained by a guide plate l ders representing thousandths and ten thou sandths of dollars in the/accumulators I05 and a lever lid, with its arm l l? carrying a pencil barrel are, is provided for each denominational order of each of the three accumulators shown (see Fig. 3). The /reason for omitting levers M5 from the orders just named is that there would be no practical value in recording on the card the iractional values standing in such orders, such orders being useful in entering labor and burden rates requiring the use of fractional values, like the example of rates given hereinaioove.

In Fig. 13 of the drawings there is shown an an example of record card I9 designed for use with the recorder disclosed herein. The card I9 is a conventional column card used with electrical accounting machines, which has been specially designed for use with the recorder of the present invention. The smaller numerals indicate the index point or digit positions of the columns which may be punched to represent data in a manner well known in the accounting machine art. The larger numerals indicate index points or digit positions used for recording by the present recorder. It is noted that the positions used by the present recorder are staggered with respect to the accounting machine positions. This'is so that data may be recorded by punching in the usual way in all of the 80 columns. 'lhe card it] is provided with three fields of the larger numerals for recording bythe present recorder, such fields being indicated by the numerals and and corresponding, respectively, to the accumulators ltd, its, and As shown, the field i3 3 is composed of three columns of digit positions for the purpose of recording on the card the time consumed on the job which is standing in the accumulator Wt. The field i33 is provided with four columns of ten digit positions for recording the money values of the labor on the job standing in accumulator The field i82 is provided with four columns reco ding the money value of the burden or overhead standing in accumulator When the card i9 is fully inserted within the card holder the lower ends of the barrels i 25 which carried the several arms iii are aligned, espectively, with the columns on the card w" it corresponds thereto which corresponds lo their related order elements of the accumulators W5, W6, and The proper (see Figs. 3 and 9) suitably fixed to the upright support plates l2 and itland formed with guide slots H38 receiving, respectively, the lower ends of the barrels 5128.

Associated with each lever lib and its arm i is a second am i which positions and operates the pencil lead Q29 in the barrel 628 of its related arm iii. The upper end of each arm Hill is formed a slot i538 (see Fig. l) receiving the shaft i W, and with an upper cam surface 539 adapted to he engaged by a cam operated hail idil when a recording is to be effected, as will presently appear. As shown in 12, the lower end of arm HST! is pivoted by a pin i 'll to one end of a rocker lever i 'id, the latter being pivoted intermediate its ends by a pin i l-3 on its related arm 3 ii" and the other end of each rocker i 32 being connected by a tension spring i s-ll to a projection N5 of its related arm it'l Each spring i 36 functions through its rocker lever ME to hold arm i871 in its normal rest position with the shaft H8 engaging the bottom or its slot I88.

As shown in Fig. 12, each pencil lead I28 is vertically movable within the bore of its barrel I28 and is connected by a spring I41 to the lower end of a rack I48 which also moves axially within the barrel. Each rack I48 is held firmly by two pawls I49 and I58 extending through slots II and I52 in the barrel I28 and engagin teeth I58 and I54, respectively, formed on opposite sides of the rack I48. The upper ends of the pawls I48 and I88 are pivoted, respectively, by the pin Ill, and by a pin I55 to the rocker lever I42. A tension spring I58 connecting tail elements I81 and I88 of the pawls I48 and I58, respectively, constantly urges the pawls into engaging relationship with their respective sets of teeth. The pivot pins I and I55, respectively, are spaced such distances from the pivot pin I48 that during each downward movement of the arm I81, the pawl I48 moves a distance equal to live of the rack teeth I58 and the pawl I88 moves a distance equal to three of the rack teeth I54. As will be noted, the teeth I54 and pawl I58 are so shaped that the rack I48 can move downward with respect to the .pawl I58 and that the pawl I58 can move upward with respect to the rack, the pawl I58 simply ratcheting over a tooth I54 into the next tooth space. However, the shape of the teeth I54 prevents upward movement of the rack with respect to the pawl I58 for a distance as much as one tooth space. The teeth I58 and pawl I49 are so shaped that they can be moved any number of tooth spaces relatively to one another in either direction When...suflicient force is applied to effect the latter, the pawl I49 will be cammed by the teeth I88 out of one tooth into the next.

When the arms I81 are moved downward by the cam operated bail I48 for the purpose of effecting a recording, in a manner which will be presently described, each pair of cooperating pawls I49 and I58 move their related rack I48 downward in the barrel I28. With a fresh lead I28 in a barrel I28, the lower end. of the lead I29 will touch the record card I9 when the rack I48 has been moved downward from the position shown a distance equal to one tooth space. When the rack has 12 space, the rack is moved upward three spaces and the pawl I49 will cam over the other two tooth spaces of its travel. As succeeding recordings are eifected the lead I29 will wear away; and, as the latter happens, the pawl I49 moves the rack I48 downward increasin distances before the resistance offered by spring I41 overcomes the force of the spring I58 and the pawl I48 cams over its teeth I58 to permit its full downward travel of five teeth. When enough lead is worn away so that the pawl I48 is permitted to move the rack the equivalent of four tooth spaces before it is cammed out of the tooth space it is occupying, the pawl I58 will then cam over a tooth I54 into the next higher tooth space. Then, as the pawl I58'wi1l only permit the rack I48 to move upward a distance of three tooth spaces on the next upward movement of the arm I31, the rack I48 and lead I28 will occupy a lower position with respect to the pawls and the lead will then have been fed downward a distance of one tooth. This feeding action will of course continue with succeedin recordings until the lead is used up and needs replacing.

Before a recorder is assigned to a Workman, an authorized person, for example his supervisor,

having a master key, not shown, unlocks the lock moved downward a second tooth space the minimum amount of compression pressure will be placed on the sprin I41 to eflect marking on the card. Further downward movement for the next or third tooth space will place additional compression pressure on the spring I41 without damaging the lead. The relative strength of the springs I41 and I58 is such that with a fresh lead further downward movement of the rack I48 beyond the three tooth spaces just mentioned, will be prevented. by the resistance ofiered by the spring I41, and the spring I58 will then yield and thereby pennit the pawl I49 to be cammed out of one tooth space'into the next. This action will permit the pawl I49 to be moved downward relative to the rack I48 a distance equal to the two additional tooth spaces of the full travel of pawl I49. At the end of downward travel, the pawl I58 will fully occupy a tooth space, the length of its travel being three tooth spaces while the pawl I48 travels dive. When the arm I31 is moved upward and back to its normal position shown the rack I 48 is raised due to the gripping force of the pawls I 49 and I58. Because the pawl I49 moves flve spaces while the pawl I58 moves three and as the shape of the teeth I54 prevent upward movement of the rack I48 with respect to the pawl I58 for a distance as much as one tooth I88 and removes the cover 21 and sets the stops 88 in the proper grooves 81 of the slots, so that for each one. tenth of an hour while the recorder is in operation, one unit of digital value will be entered in the elapsed time accumulator I81, digital values representing the workmans pay rate for one tenth of an hour will be entered ,in the labor accumuiator...I86 and. digital walues representing the burden rate for one tenth of an hour will be entered in the burden accumulator I85. After setting the stops 88 in the desired position, the cover 21 is replaced and looked and the recorder given to the workman.

When a workman begins an assigned job he eilects a start operation of the recorder I8, during which a fresh record card I8 is inserted in the card holder I5 and locked in position by the card latch lever 82. The start operation is effected by inserting a key I8I (Fig. 8) in a. key hole I82 in the end of start shaft 88 and turning the ke I8I first 60 clockwise as viewed inFig. 2 and then turning the key 68 counterclockwise back to the position shown. The card I9 is fully inserted in the card holder when the key has been turned to 60 clockwise and, as will later appear, is locked in position when the key is turned counterclockwise back to the position shown. The parts are shown in full lines in Fig. 2 in the position they occupy after a start operation has been completed. Before a start operation, a start-stop interlock element I84, which is pivoted on a stud I 85 carried by the support plate I 3, is in the dotted line position thereof shown in Fig. 2. When a start operation is begun by turning the shaft 88 clockwise 60 as above noted, the outer corner of an edge I88 of a segmental plate I81 fixed on the shaft 88, engages the lower end of a finger I88 of the pivoted interlock I84, with the latter in the dotted line position, and rotates the interlock in a counterclockwise direction about the pivot stud I85. When the interlock has been rotated counterclockwise far enough where an over-center tension spring I18, connecting a, tail element I1I of a iisi'freo in into engagement with the periphery of plate lfil. When the workman rotates the shaft 68 counterclockwise to the position shown, the lower notched end of finger H2 engages kehind the outer corner of edge I66 as shown in full lines in Fig. 2, and thereby locks the shaft 88 in the position shown. The shaft 68 can be unlocked and another start operation effected only after the workman has effected a stop operation in a manner which will appear more fully hereinafter.

When the above described 60 clockwise rotation of the shaft 68 begins, a spring-controlled detent H3 is engaged by the outer periphery of a second segmental plate in fixed to the shaft 68. so that a reverse rotation of the shaft 68 is prevented by the detent until a corner H5 of the plate l'M passes the outer end of the detent and thereby provides sufficient clearance for the detent so that its spring can return it to th position shown in Fig. 2. The latter will happen at the end of the 60 of clockwise movement. The 60 clockwise movement of th shaft 68 is limited by a stud H6 on the plate is engaging the edge ill of the-plate H4. The detent I13 is also engaged by the periphery of plate l'M when the return 60 counterclockwise movement of shaft 68 is begun and the detent thus prevents a reverse direction of movement of the shaft 88 until the 60 of counterclockwise movement is approximately completed. A stud ll'l shown in Fig. 2 as eneasing the edge We of plate H i, determines the normal position of the shaft SE3.

As shown in Fig. l, the other or left-hand end of start shaft 63 is provided with a segmental cam plate H30 fixed thereto and having a relatively high step surface iEl of greater radius and a low step surface i822 of lesser radius. A second arm W3 of the bell crank lever 55, previously described, is formed at its outer end as a cam follower and is normally held in engagement with the periphery of the cam plate ltd by the spring til. The bell crank 85 is also formed with a third arm iil l which extends upwardly and is provided at its upper end with a pivot pin we on wh ch a spring pressed dog it is pivoted. The latter is provided with a hook portion i8? normally held in engagement with the right-hand side of the arm lS i as viewed in Fig. 1, by a tension spring idd connecting a tail element Hit of the dog i238 and a stud lfiil on the arm 1184. The function of the dog illi will be explained later in connection with the description of the stop operation.

A second three-arm bell crank or lever id? is fulcrumed on the-stud 4E and comprises one arm see which operates a switch i913 connected in series with the synchronous driving motor at; a second arm Hi5 which coacts with a sprin controlled latching dog i533 pivoted on a stud idl' extending from the plate l2; and a third arm i913 having a pin H30 in the upper end thereof engaging the peripheral surface of a cam disk 260 fixed to a stop shaft lZi.

As stated hereinabove the parts are shown in the relative positions occupied when the recorder is operating. As will be explained hereinafter,

- when a stop operation is effected the lever m2 is rocked clockwise as shown in Fig. l, to a position where the outer pointed end of arm 95 thereof is latched and held latched by a projection Elli on the latching dog id e. position, an insulated projection 20? on lever arm Hi3 moves the upper end of a switch actuating member 203 to the left. This will perinit'the inherent spring force in a spring switch blade 206 to move such blade also to the leftand thereb open in moving to the latter surface of their related order ratchet wheels.

contact points 205 to stop the m tor 50. The member 203 is in the form of a flat spring plate having a greater spring force than the switch blade 204 and so mounted at its lower end that it constantly urges the switch blade in a switch closing direction, which is to the right asviewed in Fig. 1. The just described latched position of lever I92 is the ,one occupied thereby when the recorder is not operating andbefore a start operation is effected.

' With the lever I92 latched in the manner just explained. the initial rotation of the start shaft 68 by the key IS! in a clockwise direction as viewed in Fig. 2, will move the cam plate I80 counterclockwise 60" as viewed in Fig. 1, with the result that the rocker arm 45 will be rocked clockwise to move, through the linkage previously described. the arm 32 of the card latch downward as viewed in Fig. 10 and thereby clear the card slot 26. A card I!) like the one shown in Fig. 13 is then fully inserted within the slot 26 and the card holder l5 and held therein by hand while the key i6! is turned counterclockwise as viewed in Fig. 2 back to the position shown.- This will result in the cam plate m0 being rotated clockwise as viewed in Fig. l to the position shown, and in returning the rocker lever 15 and card latch arm 32 to the position shown in Figs. 1 and 10, .where the arm 32 is across the slot 26 and holding the card it in its fully inserted position.

When the cam plate M30 is rotated 60 counter clockwise as viewed in Fig. 1 during the first half of a start operation, a lug 5H0 fixed on the side of the cam plate 180 engages the lower end of latching dog l06 and moves the latter clockwise out of latching position. The spring member 203 pressing on the lower end of arm H 3 then moves the lever counterclockwise, but not far enough to close the switch points, because 2. lug 2H on arm Hi3 engages and is thereby stopped by the underside of arm id of lever which at this time is held by the high step. fill of the cam plate $230. When the shaft 68 and cam plate E86 are rotated clockwise as viewed in Fig, 1 and back to the position shown to finish the start operation. the lever 1192 will then move counterclockwise along with the lever 35 and the switch points will be closed to start the motor v During the first half of a start operation when the shaft 08 is turned for the counterclockwise movement as viewed in Fig. 4, each of the order elements having a digital value standing therein due to a previous entering operation is reset by being turned counterclockwise to the next 0 digit representing position. The latter is effected by a plurality of radially extending arms 2M fixed at their inner ends to the shaft and extending between adjacent order elements. There is one arm 2M provided for each order element l5 and it extends outwardly along the side of the order ratchet wheel from which the lugs 592 project. The arms 2 i i are made ofspring metal and engage at their outer ends the. side The lugs Q2 are wedge shaped, as shown, sothat during entering operations the low'side oflthe lugs 92 engage under the outer ends of the. spring arms and the latter are forced outwards'o that the arms El can be passed without interference...

When the start shaft 68 is turned for the 50 'counterclockwisc movement as viewed in Fig. 4. to begin the start operation, all of the arms 2M move countercockwise therewith and willengage the high sides of lugs 02 of any of the order ratchet wheels it which are positioned to represent digital shown will be opposite the lowest step I I2a'of the next segment I I I which lowest step represents the digit 0, as stated previously.

With all order elements turned to 0, and a .fresh card I9 fully inserted and locked in the card holder and with the switch contacts 208 closed. the recorder then begins to operate and will continue to operate and accumulate values in the manner above explained until the workman effects a "stop operation. He will do this when the assigned Job is completed and when work on the job is stopped for any length of time such. for example, as during lunch hour or at the end of the working day. 'When a stop operation is effected the switch contacts 208 are opened to stop the motor and the digital values standing in the accumulators are recorded in corresponding columns of the card I9. As stated hereinabove. the parts are shown in the position they occupy after the recorder has gone through one entering operation.- By way of example, the stop operation will be described as taking place with the parts in the position shown.'

A workman effects a stop operation of the recorder by inserting the key I8I in a key hole 2I5 provided in the right-hand end of stop shaft I2I (see Fig. 2) and by turning the key and shaft first,l80 counterclockwise until the edge 2|. of a segmental plate 2" fixed to the shaft I2I engages a stud 2I8 projecting from the support plate I8 and then by turning the stop shaft I2I 180 clockwise until the edge 2I9 of the plate 2i I engages the stop 2I8 as shown in Fig. 2. The stop shaft I2I is also provided with'a segmental plate 220 fixed thereto, and when the shaft I 2I is turned for 180 counterclockwise movement as viewed in Fig. 2 during the first part of the stop operation an edge 22I of the plate 228 engages the outer end of a finger 222 extending from the start stop interlock element I and moves such finger 222 and interlock I clockwise to a point where the over-center spring I" is above the axis of the pivot pin I65. When the latter happens, the spring I10 will continue the clockwise movement of the interlock I84 until the upper notched end of finger 223 engages the periphery of member 220. when the stop shaft I2I is then turned for 180' clockwise movement to complete the stop operation and to the position shown in Fig. 2. the upper notched end of finger 228 will engage the outer cprner of edge 22I of member 228 and thereby lock the shaft I2I in the stop position. The latter position of the interlock I 84 is indicated in dotted lines in Fig. 2, as was explained previously. As was the case with the start shaft, a spring controlled detent 225 coacts with the peripheral surfaces of the segmental plate 2" to assure that when either a clockwise or a counterclockwise movement of the stop shaft is commenced such movement must be completed before movement in the opposite direction can be effected.

Referring to Fig. 1, it will be apparent that the cam disk 200 on the left-hand end of the stop shaft I2I will be moved first 180 clockwise and then 180 counterclockwise, when a stop op- 16 200 for 180 clockwise movement will cause the pin I99 on the upper end of arm I98 to move out of a recess 221 in the cam 200 and onto the high surface of such cam and thereby provide for a clockwise movement of the lever I92 from the position shown. The latter will result in the arm I98 engaging the latching dog I98 to latch the lever I92 at the end of such clockwise movement, as previously explained. Also, the arm I92 will move the switch actuating member 208 to the left and thereby effect the opening of the switch contacts 20.! and stop operation of the motor I8. It Is noted that the latching of the lever I82 and the opening of contacts 205 are effected at the very beginning of each stop operation.

It is also noted that as the cam plate 200 rotates 180 clockwise to begin the stop operation, a pin 228 projecting therefrom engages the upper surface of the dog I86 and moves the latter counterclockwise about its pivot pin I88 against the force of the spring I88 until the pin- 228 clears the dog. The sprin I88 thenreturns the dog to the position shown in Fig. 1. As the cam plate 200 is rotated 180 counterclockwise as viewed in Fig. 1, back to the position shown to complete the stop operation, the pin 228 engages the inclined edge 229 of the dog I86 near the end of such movement and through the hooked end I81 of the dog engaging the right side of the lever arm I 84, moves the rocker lever 45 clockwise to effect operation of the card latch arm 82 to releas the card I9 within the card holder I5. As will be apparent from the previous description, when the rocker is moved clockwise the card latch arm 32 shown in Fig. 10 will be moved clockwise-or downward to clear the card throat and the spring fingers 28 at the right-hand end of the card holder as viewed in Fig. 9 will then partially elect the card I9 from the holder so that the card can be withdrawn the rest of the way by hand. Thus, the card I9 is released at the completion of the stop operation.

When the stop shaft I 2| is first rotated 180 counterclockwise as viewed in Fig. 2, the shaft I2I will appear in Fig. 4 as being rotated 180 clockwise and, as this happens, the bail H9 carried by the arms I20 which are fixed to the shaft I2I,

, will also move clockwise and thereby permit the arms II8 of all of the recording levers 5 to rotate clockwise under force of the springs I22 until the fingers I30 on such arms II8 engage positioning steps II2 of their related order elements 15. The levers II5 are thus positioned by the related steps I I2 and the pencil barrel I28 carried thereby will be properly positioned above the digit positions on the record card corresponding to the digit values represented by the positions of the related steps II2.

Near the end of the clockwise movement of the shaft I2I as viewed in Fig. 4, cams 232 fixed to the ends of shaft I2I (see also Fig. 5) engage arms 288 which are pivoted on studs 234 extending from the inside of the support plates I2 and I3, respectively. The arms 233 carry the bail I40 previously referred to as engaging with the upper ends of all of the pencil operating arms I31. Thus, when the cams 232 engage the arms 233 they move the latter and the bail I40 clockwise as viewed in Fig. and thereby efiect a downward movement of-all arms I31 to provide operative engagement of the pencil leads I28 with the card I9 in the manner previously described.

As shown in Figs. 2 and 3, the right-hand end of the stop shaft I2I is provided with a cam 285 eration is effected. Movement of th cam disk 76 which engages the upper end of a lever 238 ful- 17 crumed intermediate its ends on the start shaft 68. The lower end of lever 236 engages the outer end of an arm 23'! of a bell crank 238 pivoted on a stud 239 extending upwardly from the base plate H (see Figs. 2, 4, and 9). The other arm 240 of the bell crank 238 engages a pin 24! extending downwardly from the bottom plate I6 of the card holder IS. A tension spring 242 connected at one end to the pin 2 and at its other end to the upright support plate [3 maintains the pin 2 in engagement with the arm 240 of the bell crank 238 and thereby also keep arm 23! in engagement with the lower end of lever 236 and keepsthe upper end of the lever 236 in engagement with the earn 235 on the stop shaft i2l.

As will be seen from Fig. 2, when the stop shaft l2i is turned 180 counterclockwise to effect the first part of the stop operation, the high point of the cam 235 engages the upper end of the lever 236 near the end of its movement and thereby moves the latter clockwise about its fulcrum to move the bell crank 238 and th pin 2 against the force of the spring 242. As the pin 2 is fixed to the card holder l5, such movement will result in the card holder being moved to the left as viewed in Fig, 9. When the stop shaft l2l is then rotated 18 clockwise as viewed in Fig. 2 to complete the stop operation, the upper end of the lever 236 will move from the high point of the cam 235 during the first part of this movement and back to the position shown, which will result in the spring 242 returning the card holder [5 to the position shown in Fig. 9. The just described movement of the card holder 15 to the left, as viewed in Fig. 9, during the latter part of the counterclockwise movement as viewed in Fig. 2, of shaft HI, and the return movement of the card holder to the position shown during the first part of the clockwise movement of shaft i2l, occurs at a time when theleads I29 are held in engagement with the card l9 by the bail I40 and arms I31, as previously described. Thus, such movement of the card holder results in electrically conducting marks being placed on the card in the index points or digit positions of the columns of the card determined by the digit representing positions of the steps I I2 of their related star wheels I I0.

As stated, the stop operation is described herein as taking place after one entering operation has been effected. Consequently, electrically conducting marks are placed on the card IS in the index point positions of the columns to represent the amounts standing in the three accumulators after one entering operation. Fig. 13 shows the card with the amounts recorded thereon. The electrically conducting marks are indicated by the reference character 245.

Record cards having numerical data recorded therein by the time recorder of the present invention and in the manner described hereinabove, may be used in apparatus of the type disclosed in U. S. patent to Bryce 2,007,391 and Johnson 2,275,396, wherein they will control the unching of numerical code hole designations in the index point positions of standard electrical accounting machine cards.
